Inventor: CLAYTON AYERS JUN ROBERT
IPC: C12M1/12
Filed: 1968-11-05
Abstract: The process relates to the purification and concentration of the moderately proteolytic, milk-clotting enzyme which is formed by Endothia parasitica, or the proteolytic enzyme which is formed by Bacillus subtilis, by a reversed osmosis method. A soln. of the impure enzyme is brought into contact with one side of a semi-permeable membrane, through which the enzyme cannot pass but which is permeable to solvent, inorganic salts and low-molecular organic compounds. Sufficient pressure is applied to the enzyme soln. to cause the solvent to pass through the membrane, so that the enzyme is retained by the membrane, in contrast to the solvent, the inorganic salts and the organic compounds. The pure enzyme is obtd. in high yields. The process avoids the use of increased temps.
